PERCY FALKINBURG, OF ATLANTIC IIIGHLANDS, NEV JERSEY.

FLUSH-*TANK FOR CLOSETS.

SPECIFICATION forming part of Letters Patent No. 495,611, dated April 18, 1893.

Application filed January 14, 1893. Serial No. 458,400. (No model.)

To LZZ whom t may concern.:

Be it known that I, PERCY FALKINBURG, a citizen of the United States, residing at At-` lantic Highlands, in the county ol" Monmouth, State of New Jersey, have invented certain new and useful Improvements in Flush-Tanks for Closets; and I do hereby declare the following to be a full, clear, and exact descrip-` tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to flush tanks for water closets.

The object of the invention is to prevent Waste of water, secure a good flush and enable the use of an air tight tank.

The invention consists of the novel features and the peculiar construction and combination of the parts which will be hereinafter more fully described and claimed and which are shown in the annexed drawings,in which;

Figure l is a diagrammatical view of the invention. Fig. 2 is a detail view of the valve which is opened by the pressure on the closet seat and closed by a spring.

The tank A is air tight and is provided on its top side with a hand hole B which is closed by a screw cap b. Vtithin this tank is located the mechanism for controlling the supply of water to the closet. The supply pipe D projects vertically into the tank and is provided at its upper end with a cup d which is designed to receive a float e at one end of the lever E. The valve f for closing the upper end of the flush pipe I-I is carried by the rod F which is attached at its upper end to the opposite end of the lever E. This lever E is pivoted between its ends to a standard or other suitable support C rising from the bottom of the tank A. The guide G is provided to insure the closing of the valve f on the seat provided at the upper end of the flush pipe I-I and guides the rod F in its movements. The iiush pipe I-I extends from the bottom side of the tank A and connects with the closet in the usual manner. i

The spring actuated valve I is suitably located in the supply pipe D and is adapted to be pressed upon to cause a supply of water to the tank A. This valve I is normally held closed by means of a spring c" and is opened by pressure of the seat on the valve stem e' which overcomes the force of the spring i.

A small waste pipe J connects the valve I with the fiush pipe H, the parts being so disposed that when the valve I is open to admit a supply of water to the tank A the waste pipe J will be closed and when the said valve I is closed the waste pipe J will be opened to permit the water in the cup d and in the upper portion ot thesupplyfppe to escape for the purpose presently to be described.

The operation of the invention is as follows: The valve I being opened by pressure on the closet seat permits the water to dow into the cup d and fill the same and overflow-into the tank A. As the cup d fills ,with water the lioat e rises and causes the valve f to close the upper end of the Hush. pipe H. The Water will continue to overflow the cup d and enter the tank untilthe atmospheric pressure in the said tank A will equal the pressure of the flow of water when the supply will cease notwithstanding the valve I remains open. When the pressure is removed from the seat the valve I will close and shut oit the supply of water and the waste pipe J will be opened. The Water in the cup d and in the upper portion of the supply pipe D will escape and permit the fioat e to fall thereby unseating the valve f and permitting the water confined in the tank A to escape through the iush pipe Il. The air confined under pressure in the tank A facilitates the discharge of the water from the cup d through the pipe J and at the saine time gives an impetus to the water escaping through the flush pipe I-I.

Any form of valve that is provided with au escape or waste as J and which is adapted to be operated by pressure on the valve stem and which valve when open will close the waste J and when closed will open the waste J, may be substituted for the valve I have herein shown and described.

To prevent the suction in the pipe II from seating the valvef a small air pipe h will be provided and located at the head of the said iiush pipe I-I to admit air.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is'- 1. The combination with an air tight tank IOO for flushing closets, of asupply pipe having a cup at its delivery end, the flush pipe communicating with said tank, and alevercarrying a valve at one end to close the flush pipe, and provided with a float at its other end, which oat is adapted to rest in the said cup at the delivery end of the supply pipe when the water is shut off from the said supply pipe, substantially as and for the purpose herein specified.

2. In a flushing closet the combination with a tank having the flush pipe connected therewith, and a lever carrying avalve for closing the said flush pipe, of a float carried by the said lever, and the supply pipe havingits delivery end directly underthe said float whereby the pressure and force of the inflowing water against the said ioat will assist in closing the valveon the flush pipe, substantially as set forth.

3. In a flushing closet the combination of a tank, flush pipe communicating with said tank, a valve for closing the flush pipe, a lever carrying the said valve and provided with a float, a supply pipe having a cup at its delivery end to receive the said float, aV valve connected with the said supply pipe and adapted to be operated by pressure on the closet seat, and a Waste pipe connected with the said valve and adapted to be closcd'when the said valve is open andl vice versa, substantially as set forth.

4. The herein described means for flushing closets consisting of an air tight tank, a flush pipe communicating with the lower portion of the said tank, avalve adapted to close said iiush pipe, a guide to insure the seating of the said valve, the lever having the said valve connected therewith, a float attached to the said lever, a supply pipe having a cup at its delivery end to receive the said iloat, avalve for controlling the supply of water through the supply pipe, and a waste pipe connected with the said valve for the purpose of drainjing the said cup and upper portion of the supply pipe, substantially as described for lthe purpose set forth.

5. In a flushing closet the combination of an air tight tank, a lever pivotally supported between its ends and provided with a Heat at lone end andY a valve at the opposite end, a :supply pipe having its delivery end directly beneath the float, and a flush pipe adapted to be closed by the said valve and provided at its upper end with an air tube to prevent the suction seating the said valve when ilushing the closet, substantially as set forth.

In testimony whereof I'affix my signature in presence of two witnesses.
